Haematological Traits of Nigerian Indigenous Pig and Its Hybrid (50% Large White × 50 NIP) at Post Weaning Ages
Abstract: Pigs play a major role in socioeconomic life of the people; it serves as a source of income for rural population and fulfill important role in culture and food security. Fifty-one weaners were randomly selected at 9, 17 and 25 weeks of age for analysis. Blood from the jugular vein of the weaners was taken to the laboratory for analysis. The leaukocyte parameters used for this study were White blood cell count (WBC), Lymphocyte (LYM) count, Neutrophil (NEU) count, Eosinophil (EOS) and Monocyte (MON) count) and Platelet (PLT) count. Data collected on these leaukocyte parameters were subjected to Analysis of Variance (ANOVA) while the means were separated using Duncan’s Multiple Range Test. The results showed that at 9 weeks of age, compared with the female hybrid, the male hybrid had higher PCV, NEU and EOS (33.12% ± 2.73%, 31.00% ± 3.37% and 0.38% ± 0.18% respectively) values, while the female NIP had higher WBC, LYM and MON (24.55 ± 1.09 × 103/μl, 56.00% ± 3.24% and 0.50% ± 0.50%) values respectively. At 17 weeks of age, the male hybrid had higher WBC and NEU (32.18 ± 1.92 × 103/μl and 32.38% ± 3.56%) values while the female had higher PCV, LYM, EOS and MON (42.50% ± 1.50%, 63.00% ± 5.0%, 2.50% ± 2.50% and 4.50% ± 1.50%) values. At 25 weeks of age, the female hybrid had higher values in all the parameters with the exception of NEU and MON where male had higher values. These ages can be used as criteria for selection for immunocompetence in pigs.
